The rudder had some gotchas which needed special attention. The 4 skin rivets next to the “Rudder Control Bracket” (12) are hard to rivet, when the rudder control bracket is installed. So I omitted “Step 6” in the KAI and installed the bracket after riveting the skin. I would also recommend installing the “Rudder Counterbalance Weight” (2) after putting the rudder skin (14) on instead of doing it in “Step 2”. The “Rudder Counterbalance Weight” adds a lot of weight to a flimsy structure.
